Left AirPods Pro 2 only charges after a reset

iphone 16 pro, airpod pro 2 (buy one year ago, last firmware)

Each time i must reset my airpod pro2 if i want to charge the left side

the right side havent’ got this problem.

Day 1 : i want to use my air pod pro2, i see that the left was at 0%.

i clean the case, clean the left airpod

still dont charge.

I reset my air pod pro2 (disconnected from my iphone, and connected it), the left side charge well.

Day 2 : same problem

day 3 : same problem

….

now each time i want to use my AirPod pro 2.

i must unconnected it, reconnect it, charge the left side, use it
